Create a text element

By Augusto Goncalves

The method Create.NewTextNote of the Document class is the key to create a text node element. This sample code additionally gets the curve information of elements to align the text.

// Get the active document and view

UIDocument uiDoc = commandData.Application.ActiveUIDocument;

Document doc = uiDoc.Document;

View view = uiDoc.ActiveView;

 

foreach (Element elem in uiDoc.Selection.Elements)

{

  // skip elements without curve

  if (!(elem.Location is LocationCurve)) continue;

 

  // get the curve of the element

  Curve curve = ((LocationCurve)elem.Location).Curve;

 

  // Calculate necessary auguments

  XYZ origin = curve.get_EndPoint(0);

  XYZ baseVec = XYZ.BasisX;

  XYZ upVec = XYZ.BasisZ;

  double textSize = curve.Length / 10;

  double lineWidth = curve.Length / 50;

  string strText = "This is " + elem.Name;

 

  // Create the text

  TextNote text = doc.Create.NewTextNote(view, origin,

    baseVec,

    upVec,

    lineWidth,

    TextAlignFlags.TEF_ALIGN_CENTER |

    TextAlignFlags.TEF_ALIGN_MIDDLE, strText);

  text.Width = curve.Length * 10; // set the width of the text

}
